MongoGridFS::storeUpload

Description

Parameters

name

The name of the uploaded file(s) to store. This should correspond to the
file field's name attribute in the HTML form.

metadata

Other metadata fields to include in the file document.

Note:

These fields may also overwrite those that would be created automatically by the driver, as described in the MongoDB core documentation for the » files collection. Some practical use cases for this behavior would be to specify a custom chunkSize or _id for the file.

Note:

The filename field will be populated with the
client's filename (e.g. $_FILES['foo']['name']).

Return Values

Returns the _id of the saved file document. This will be a generated MongoId unless an _id was explicitly specified in the metadata parameter.

User Contributed Notes 2 notes

For my PHP 7.0.27 this is incompatible to the "multiple" tag on inputs.

Like this:

<input type="file" name="files[]" multiple>

Please note that you need to use 'files[]', as else only one file is used from the uploaded files.

As documented, you need to give the Index into $_FILES as the first argument to this function. Like in:

foreach ($_FILES as $k=>$v) $db->getGridFS()->storeUpload($k, $v);

However in the case of "multiple" selects, the corresponding entry in $_FILES[$k]["name"] is an array of filenames, not just a single filename. This is true even for a single file, in that case it is an array with just a single string in it.

In that case the function just silently fails. No error, no problem shown, it just becomes a NOP.

The workaround is:

- Without JavaScript, fallback to single file upload.- With JavaScript add "multiple", and do the upload with Ajax file-by-file.- As then only single files reach PHP, the problem is solved.
